My store is powered by Shopify who are certified Level 1 PCI DSS compliant.
The Payment Card Industry Data Security Standard (PCI DSS) is a security standard for organizations that handle credit and debit card information. The standard was created to increase controls around payment data to reduce fraud.
Shopify are very serious about securely hosting my store and have invested significant time and money to certify their solution is PCI compliant. From annual on-site assessments validating compliance to continuous risk management, they work hard to keep my shopping cart and ecommerce hosting secure.
I wouldn't trust any other way of taking payments for my products and services. You will have peace of mind that all your personal details are protected and the only detail i use is your email address only if you gave me permission to send you my monthly newsletter.
